Microsoft, inventor of the GUI operating system "Windows", was officially declared a monopoly by the US District Judge Thomas Penfield Jackson. Jackson declared that Microsoft had a monopoly over the Operating System (OS) market, and hurt consumers with their non-competitive behavior. Judge Jackson also found that several innovations that would have been to the advantage of the consumer were shot down by Microsoft because it did not promote their self-interests.

Microsoft was then broken into two companies: An Operating System company, and a Software/Applications company. The two new companies were then disallowed to make 1 to 1 trades with one another, allowing other Operating Systems, such as Macintosh OS, to use Microsoft Office, an extremely popular software package.
